A Randomized Crossover Trial Evaluating the Impact of Cultural Dexterity Training on Surgical Residents' Knowledge, Cross-Cultural Care, Skills, and Beliefs: The Provider Awareness and Cultural dexterity Training for Surgeons (PACTS) Trial.

OBJECTIVES: This trial examines the impact of the Provider Awareness and Cultural dexterity Toolkit for Surgeons (PACTS) curriculum on surgical residents' knowledge, cross-cultural care, skills, and beliefs. SUMMARY BACKGROUND DATA: Cross-cultural training of providers may reduce healthcare outcome disparities, but its effectiveness in surgical trainees is unknown. METHODS: PACTS focuses on developing skills needed for building trust, working with patients with limited English proficiency, optimizing informed consent, and managing pain. The PACTS trial was a randomized crossover trial of 8 academic general surgery programs in the United States: The Early group ("Early") received PACTS between Periods 1 and 2, while the Delayed group ("Delayed") received PACTS between Periods 2 and 3. Residents were assessed pre- and post-intervention on Knowledge, Cross-Cultural Care, Self-Assessed Skills, and Beliefs. Chi-square and Fisher's exact tests were conducted to evaluate within- and between-intervention group differences. RESULTS: Of 406 residents enrolled, 315 were exposed to the complete PACTS curriculum. Early residents' Cross-Cultural Care (79.6% to 88.2%, P<0.0001), Self-Assessed Skills (74.5% to 85.0%, P<0.0001), and Beliefs (89.6% to 92.4%, P=0.0028) improved after PACTS; Knowledge scores (71.3% to 74.3%, P=0.0661) were unchanged. Delayed resident scores pre- to post-PACTS showed minimal improvements in all domains. When comparing the two groups at Period 2, Early residents had modest improvement in all 4 assessment areas, with statistically significant increase in Beliefs (92.4% vs 89.9%, P=0.0199). CONCLUSION: The PACTS curriculum is a comprehensive tool that improved surgical residents' knowledge, preparedness, skills, and beliefs, which will help with caring for diverse patient populations.

The Relationship Between Peripheral Arterial Disease Severity and Socioeconomic Status.

BACKGROUND: Although socioeconomic disparities in outcomes of peripheral artery disease (PAD) have been well studied, little is known about relationship between severity of PAD and socioeconomic status. The objective of this study was to examine this relationship. METHODS: Patients who had operations for severe PAD (rest pain or tissue loss) were identified in the National Inpatient Sample, 2005-2014. They were stratified by the median household income (MHI) quartiles of their residential ZIP codes. Other characteristics such as race/ethnicity and insurance type were extracted. Factors associated with more severe disease (tissue loss) were evaluated using multivariable regression analyses. RESULTS: There were 765,175 patients identified; 34% in the first MHI quartile and 18% in the fourth MHI quartile. Compared to patients in the first quartile, those in the fourth quartile were more likely White (69% vs. 42%, P < 0.001), more likely ≥65 years old (75% vs. 62%, P < 0.001), and were less likely to undergo amputations (25% vs. 34%, P < 0.001). After adjusting for patient characteristics, the fourth quartile was associated with more severe disease [Odds ratio: 1.19, 95% confidence interval (CI): 1.11-1.27] compared to the first quartile. CONCLUSIONS: While higher MHI was associated with higher PAD severity, patients with high MHI were less likely to undergo amputations indicating a disparity in the choice of treatment for PAD. Increased efforts are necessary to reduce socioeconomic disparities in the treatment of severe PAD.

The Role of Body Mass Index and Hypoalbuminemia on Postoperative Outcomes in Patients Undergoing Total Knee Arthroplasty.

Obesity and malnutrition are modifiable risk factors associated with increased postoperative complications following total knee arthroplasty (TKA). Obesity is paradoxically associated with malnutrition. Previous studies have only evaluated the impact of body mass index (BMI) and hypoalbuminemia separately in relation to postoperative TKA outcomes and have attempted to compare the impact of these modifiable risk factors. Our study seeks to establish if increased BMI and decreased albumin levels have a compounding effect on postoperative outcomes. A retrospective analysis was conducted using the 2011-2014 American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) dataset. This study reaffirmed that increased BMI and low albumin levels are associated with increased postoperative complications following TKA. Moreover, this study demonstrated that they do not have a compounding effect, but rather only help predict outcomes when analyzed individually.

The influence of socioeconomic status on outcomes of lower extremity arterial reconstruction.

OBJECTIVE: Although it has been shown that patient socioeconomic status (SES) is associated with the surgical treatments chosen for severe peripheral arterial disease (PAD), the association between SES and outcomes of arterial reconstruction have not been well-studied. The objective of this study was to determine if SES is associated with outcomes following lower extremity arterial reconstruction. METHODS: Patients 40 years and older who had surgical revascularization for severe lower extremity PAD were identified in the Nationwide Readmissions Database, 2010 to 2014. Measures of SES including median household income (MHI) quartiles of patients' residential ZIP codes were extracted. Factors associated with repeat revascularization, subsequent major amputations, hospital mortality, and 30-day all-cause readmission were evaluated using multivariable regression analyses. RESULTS: Of the 131,529 patients identified, the majority (61%) were male, and the average age was 69 years. On unadjusted analyses, subsequent amputations were higher among patients in the lowest MHI quartile compared with patients in the highest MHI quartile (13% vs 10%; overall P < .001). On multivariable analyses, compared with patients in the lowest quartile, those in the highest quartile had lower amputation (adjusted odds ratio [aOR], 0.70; 95% confidence interval (CI), 0.63-0.77; overall P < .001) and readmission (aOR, 0.91; 95% CI, 0.84-0.99; overall P = .028) rates. However, subsequent revascularization (aOR, 1.04; 95% CI, 0.94-1.15) and mortality (aOR, 1.01; 95% CI, 0.79-1.28) rates were not different across the groups. CONCLUSIONS: Lower SES is associated with disproportionally worse outcomes following lower extremity arterial reconstruction for severe PAD. These data suggest that improving outcomes of lower extremity arterial reconstruction may involve addressing socioeconomic disparities.

Patterns and Trends of Gun Violence Against Women in the United States.

OBJECTIVE: To examine patterns and trends of firearm injuries in a nationally representative sample of US women. SUMMARY OF BACKGROUND DATA: Gun violence in the United States exceeds rates seen in most other industrialized countries. Due to the paucity of data little is known regarding demographics and temporal variations in firearm injuries among women. METHODS: Data were extracted from the Centers for Disease Control and Prevention's Web-based Injury Statistics Query and Reporting System (2001-2017) for women 18 years and older. Number of nonfatal firearm assaults and homicide per year were extracted and crude population-based injury rates were calculated. Sub-stratification by age-group and time period were performed. RESULTS: Between 2001 and 2017, there were 88,823 nonfatal firearm assaults involving women and 29,106 firearm homicides. There were 4116 victims of nonfatal firearm assault in 2001 (3.8 per 105) and 12,959 by 2017 (10.0 per 105). Homicide rates were 1.5 per 105 in 2001 and 1.7 per 105 in 2017. Sub-stratification by age-group and time period showed that there were no significant changes in nonfatal firearm assault rates between 2001 and 2010 (P-trend = 0.132 in 18-44 yo; 0.298 in 45-64 yo). However between 2011 and 2017, nonfatal assault rates increased from 7.10 per 105 to 19.24 per 105 in 18-44 yo (P-trend = 0.013) and from 1.48 per 105 to 3.93 per 105 in 45-64 yo (P-trend = 0.003). Similar trends were seen with firearm homicide among 18-44 yo (1.91 per 105 to 2.47 per 105 in 2011-2017, P-trend = 0.022). However, the trends among 45-64 yo were not significant in both time periods. CONCLUSIONS: Female victims of gun violence are increasing and more recent years have been marked with higher rates of firearm injuries, particularly among younger women. These data suggest that improved public health strategies and policies may be beneficial in reducing gun violence against US women.

Coronary Artery Bypass Grafting Among Older Adults: Patterns, Outcomes, and Trends.

INTRODUCTION: Although the numbers of older adults in the US are rapidly increasing, there is sparse recent data on the use and outcomes of coronary artery bypass grafting (CABG) among this population. We aimed to evaluate the characteristics and outcomes of older adults undergoing CABG and to measure temporal trends. MATERIALS AND METHODS: Using data from the National Inpatient Sample (2005-2014), patients aged 85 y and older who underwent CABG were selected. Demographic, clinical, and hospital characteristics were extracted. Outcomes measured were hospital mortality, hospital length of stay, discharge home, and operative complications. Patients were grouped by 2-year increments. Differences in clinical characteristics and outcomes over time were evaluated using trend analyses. RESULTS: There were 60,124 patients included in the cohort. The mean age was 86.8 y with majority being men (61%), white (88%), and treated in teaching hospitals (61%). Over the study period, the annual surgical volume decreased from 6689 in 2005/06 to 5150 in 2013/14. Mortality decreased from 8.5% to 5.5% (P-trend <0.001) and mean hospital length of stay decreased from 13.9 d to 12.0 d (P-trend <0.001), whereas the rate of discharge home remained stable (14.1% versus 11.6%, P-trend = 0.056). Compared with patients in 2005/06, those in 2013/14 had higher comorbidities [diabetes: 27.6% versus 17.3%; chronic kidney disease: 29.8% versus 9.2%; peripheral artery disease: 7.5% versus 6.0%; and hypertension: 83.7% versus 64.5% (all P-trend <0.001)]. CONCLUSIONS: CABG volumes are decreasing among older adults, and comorbidity burden is increasing, but outcomes are improving. These data may indicate improved preoperative optimization and better perioperative care processes.

Risk Factors Associated With Adverse Outcomes After Ventral Hernia Repair With Component Separation.

BACKGROUND: Over 350,000 surgeries are performed for ventral hernias (VHs) annually. Abdominal wall component separation has been more frequently used for the management of VHs. The goal of this study is to better understand factors associated with component separation complication rates. METHODS: The National Inpatient Sample (2005-2014) was used to identify all patients with an International Classification of Diseases ninth Revision diagnosis of VHs who underwent open VH repair with a pedicleor graft advancement flap. All cases included in this study were elective and not associated with additional procedures. Demographic, clinical, and hospital characteristics were extracted. Independent predictors of complications and outcomes were determined by multivariable regression analysis. RESULTS: Component separation was performed in 4346 patients. Mean age was 56; majority were female (55%) and white (80%). Most patients (73%) underwent surgery in an urban teaching hospital; mesh was used in 80% of cases and 11% were smokers. Hypertension was the most common comorbidity (50%), followed by obesity (26%), diabetes mellitus (DM) (23%), coronary artery disease (11%), and chronic obstructive pulmonary disease (COPD) (8%). Half of the patients (50%) had private insurance, and 35% had Medicare. Patients were distributed equally over household income quartiles. The mortality rate was 0.5%; median length of stay was 5 d. Overall complication rate was 25% (wound 11%, intraoperative 5%, infectious 11%, and pulmonary 8%). Mesh was associated with a lower rate of wound complications (10% versus 15%, P = 0.001). On multivariable analysis, patients with COPD (odds ratio: 2.02; 95% confidence interval: 1.58-2.59), obesity (1.37; 1.16-1.63), DM (1.3; 1.09-1.55), and those in the lowest income quartile (1.44; 1.06-1.96) had higher overall complication rates. CONCLUSIONS: Consistent with other studies, patients with COPD, Obesity, DM, and lower income status were associated with increased complications after component separation.

The Potential Impact of Plastic Surgery Expertise on Body Contouring Procedure Outcomes.

BACKGROUND: With the increasing demand for body contouring procedures in the United States over the past 2 decades, more surgeons with diverse specialty training are performing these procedures. However, little is known regarding the comparative outcomes of these patients. OBJECTIVES: The purpose of this study was to compare outcomes of body contouring procedures based on the specialty training of the surgeon. METHODS: Data from the American College of Surgeons National Surgical Quality Improvement Program (2005-2015) were reviewed for all body contouring procedures. Patients were stratified by surgeon training (plastic surgery [PS] vs general surgery [GS]). Descriptive statistics and regression analyses were used to evaluate differences in outcomes. RESULTS: A total of 11,658 patients were included; 9502 PS cases and 2156 GS cases. Most were women (90.4%), aged 40 to 59 (52.7%) and white (79.5%). Compared with PS patients, GS patients were more likely to be obese (61.4% vs 40.6%), smokers (13.6% vs 9.8%), and with ASA classification ≥3 (35.3% vs 18.6%) (all P < 0.001). Abdominal contouring procedures were the most common (76%) cases. Multivariate regression revealed that compared with PS cases, those performed by GS practitioners were associated with increased wound and infectious complications (adjusted odds ratio [aOR], 1.81; 95% confidence interval [CI], 1.44-2.27), reoperation (aOR, 1.85; 95% CI, 1.31-2.62), and predicted mean length of stay (1.12 days; 95% CI, 0.64-1.60 days). CONCLUSIONS: The variable outcomes in body contouring procedures performed by PS compared with GS practitioners may imply procedural-algorithmic differences between the subspecialties, leading to the noted outcome differential.

Trends in Firearm Injuries Among Children and Teenagers in the United States.

BACKGROUND: Gun violence among children and teenagers in the United States occurs at a magnitude many times that of other industrialized countries. The trends of injury in this age group relative to the adult population are not well studied. This study seeks to measure trends in pediatric firearm injuries in the United States. METHODS: Data from the National Trauma Data Bank (2010-2016) were used in selecting patients evaluated for firearm injury. Patients were classified as children and teenagers (<20 y) or adults (≥20 y). Changes in the proportion of firearm injuries among children and teenagers relative to the overall population (pediatric component) were determined using trend analyses. RESULTS: There were 240,510 firearm injuries with children and teenagers accounting for 45,075 of these injuries (pediatric component of 18.7%). Pediatric firearm injury was mostly among males (87.4%), Blacks (60.7%), and victims of assault (76.0%). The pediatric component of firearm injuries decreased from 21.7% in 2010 to 18.2% in 2016 (P-trend < 0.001). Although there was a decrease from 22.7% to 17.6% in the pediatric component of assault (P-trend < 0.001), there was an increase from 8.7% to 10.1% in the pediatric component of self-inflicted injuries (P-trend = 0.028). Substratification by race/ethnicity showed decrease in the pediatric component of firearm injuries among all groups (P-trend < 0.001) except Whites (P-trend = 0.847). CONCLUSIONS: Despite reductions in the pediatric component of firearm injuries, there remains a significant burden of injury in this group. Continued public health efforts are necessary to ensure safety and reduce firearm injuries among children and teenagers in the United States.

Are we doing too many non-therapeutic laparotomies in trauma? An analysis of the National Trauma Data Bank.

BACKGROUND: Exploratory laparotomy (EL) has been the definitive diagnostic and therapeutic modality for operative abdominal trauma in the US. Recently, many trauma centers have started using diagnostic laparoscopy (DL) in stable trauma patients in an effort to reduce the incidence of non-therapeutic laparotomy (NL). We aim to evaluate the incidence of NL in the trauma population in the US and compare the outcomes between DL and NL. METHODS: Using ICD-9 codes, the National Trauma Data Bank (2010-2015) was queried for patients undergoing any abdominal surgical intervention. Patients were divided into two groups: diagnostic laparoscopy (DL) and exploratory laparotomy (EL). Hemodynamically unstable patients on arrival and patients with abbreviated injury score (AIS) > 3 were excluded. Patients in EL group without any codes for gastrointestinal, diaphragmatic, hepatic, splenic, vascular, or urological procedures were considered to have undergone NL. After excluding patients who were converted to open from the DL group, multivariate regression models were used to analyze the outcomes of DL vs NL group with respect to mortality, length of stay, and complications. RESULTS: A total of 3197 patients underwent NL vs 1323 patients who underwent DL. Compared to DL group, the NL group were older (mean age: 35 vs. 31, P < 0.01). Rate of penetrating injury was 77% vs 86% for patients in NL vs DL. On multivariate analysis, NL was associated with increased mortality (OR 4.5, 95% CI 2.1-9.7), higher rate of complications (OR 2.2, 95% CI 1.4-3.3), and a longer hospital stay (OR 2.7, 95% CI 2.1-3.5). NL was also associated with higher rates of pneumonia, VTE, ARDS, and cardiac arrest. CONCLUSION: With increasing experience in minimally invasive surgery, DL should be a part of the armamentarium of trauma surgeons. This study supports that in well-selected trauma patients DL has favorable outcomes compared to NL. These findings warrant further investigation.

Assessment of the "Weekend Effect" in Lower Extremity Vascular Trauma.

BACKGROUND: Studies suggest that patients admitted on weekends may have worse outcomes as compared with those admitted on weekdays. Lower extremity vascular trauma (LEVT) often requires emergent surgical intervention and might be particularly sensitive to this "weekend effect." The objective of this study was to determine if a weekend effect exists for LEVT. METHODS: The National and Nationwide Inpatient Sample Database (2005-2014) was queried to identify all adult patients who were admitted with an LEVT diagnosis. Patient and hospital characteristics were recorded or calculated and outcomes including in-hospital mortality, amputation, length of stay (LOS), and discharge disposition were assessed. Independent predictors of outcomes were identified using multivariable regression models. RESULTS: There were 9,282 patients admitted with LEVT (2,866 weekend admissions vs. 6,416 weekday admissions). Patients admitted on weekends were likely to be younger than 45 years (68% weekend vs. 55% weekday, P < 0.001), male (81% weekend vs. 75% weekday, P < 0.001), and uninsured (22% weekend vs. 17% weekday, P < 0.001) as compared with patients admitted on weekdays. There were no statistically significant differences in mortality (3.8% weekend vs. 3.3% weekday, P = 0.209), amputation (7.2% weekend vs. 6.6% weekday, P = 0.258), or discharge home (57.4% weekend vs. 56.1% weekday, P = 0.271). There was no clinically significant difference in LOS (median 7 days weekend vs. 7 days weekday), P = 0.009. On multivariable regression analyses, there were no statistically significant outcome differences between the groups. CONCLUSIONS: This study did not identify a weekend effect in LEVT patients in the United States. This suggests that factors other than the day of admission may be important in influencing outcomes after LEVT.

The Role of Body Mass Index in Perioperative Complications Among Patients Undergoing Total Knee Arthroplasty.

Obesity is a modifiable risk factor that causes mechanical forces to be exerted within the joints, further contributing to the debilitating effects of osteoarthritis. Total Knee Arthroplasty (TKA) can have a profound impact on patients with osteoarthritis, providing them with increased quality of life, improved function, reduction of pain, while simultaneously preventing the development of additional comorbidities. Although there is inconclusive evidence that increased body mass index (BMI) is linked to increased perioperative complications among TKA patients, recent studies suggest this association exists. The aim of this study is to provide conclusive data on the effects of BMI on perioperative complications in TKA using the national risk-adjusted database, ACS-NSQIP. Our study demonstrated that there was a correlation between increased BMI and perioperative outcomes, particularly with surgical site infections, renal, and respiratory complications. (Journal of Surgical Orthopaedic Advances 29(4):205-208, 2020).

Failure to rescue and disparities in emergency general surgery.

BACKGROUND: Racial and socioeconomic disparities are well documented in emergency general surgery (EGS) and have been highlighted as a national priority for surgical research. The aim of this study was to identify whether disparities in the EGS setting are more likely to be caused by major adverse events (MAEs) (e.g., venous thromboembolism) or failure to respond appropriately to such events. METHODS: A retrospective cohort study was undertaken using administrative data. EGS cases were defined using International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes recommended by the American Association for the Surgery of Trauma. The data source was the National Inpatient Sample 2012-2013, which captured a 20%-stratified sample of discharges from all hospitals participating in the Healthcare Cost and Utilization Project. The outcomes were MAEs, in-hospital mortality, and failure to rescue (FTR). RESULTS: There were 1,345,199 individual patient records available within the National Inpatient Sample. There were 201,574 admissions (15.0%) complicated by an MAE, and 12,006 of these (6.0%) resulted in death. The FTR rate was therefore 6.0%. Uninsured patients had significantly higher odds of MAEs (adjusted odds ratio, 1.16; 95% confidence interval, 1.13-1.19), mortality (1.28, 1.16-1.41), and FTR (1.20, 1.06-1.36) than those with private insurance. Although black patients had significantly higher odds of MAEs (adjusted odds ratio, 1.14; 95% confidence interval, 1.13-1.16), they had lower mortality (0.95, 0.90-0.99) and FTR (0.86, 0.80-0.91) than white patients. CONCLUSIONS: Uninsured EGS patients are at increased risk of MAEs but also the failure of health care providers to respond effectively when such events occur. This suggests that MAEs and FTR are both potential targets for mitigating socioeconomic disparities in the setting of EGS.

Impact of public release of performance data on the behaviour of healthcare consumers and providers.

BACKGROUND: It is becoming increasingly common to publish information about the quality and performance of healthcare organisations and individual professionals. However, we do not know how this information is used, or the extent to which such reporting leads to quality improvement by changing the behaviour of healthcare consumers, providers, and purchasers. OBJECTIVES: To estimate the effects of public release of performance data, from any source, on changing the healthcare utilisation behaviour of healthcare consumers, providers (professionals and organisations), and purchasers of care. In addition, we sought to estimate the effects on healthcare provider performance, patient outcomes, and staff morale. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and two trials registers on 26 June 2017. We checked reference lists of all included studies to identify additional studies. SELECTION CRITERIA: We searched for randomised or non-randomised trials, interrupted time series, and controlled before-after studies of the effects of publicly releasing data regarding any aspect of the performance of healthcare organisations or professionals. Each study had to report at least one main outcome related to selecting or changing care. DATA COLLECTION AND ANALYSIS: Two review authors independently screened studies for eligibility and extracted data. For each study, we extracted data about the target groups (healthcare consumers, healthcare providers, and healthcare purchasers), performance data, main outcomes (choice of healthcare provider, and improvement by means of changes in care), and other outcomes (awareness, attitude, knowledge of performance data, and costs). Given the substantial degree of clinical and methodological heterogeneity between the studies, we presented the findings for each policy in a structured format, but did not undertake a meta-analysis. MAIN RESULTS: We included 12 studies that analysed data from more than 7570 providers (e.g. professionals and organisations), and a further 3,333,386 clinical encounters (e.g. patient referrals, prescriptions). We included four cluster-randomised trials, one cluster-non-randomised trial, six interrupted time series studies, and one controlled before-after study. Eight studies were undertaken in the USA, and one each in Canada, Korea, China, and The Netherlands. Four studies examined the effect of public release of performance data on consumer healthcare choices, and four on improving quality.There was low-certainty evidence that public release of performance data may make little or no difference to long-term healthcare utilisation by healthcare consumers (3 studies; 18,294 insurance plan beneficiaries), or providers (4 studies; 3,000,000 births, and 67 healthcare providers), or to provider performance (1 study; 82 providers). However, there was also low-certainty evidence to suggest that public release of performance data may slightly improve some patient outcomes (5 studies, 315,092 hospitalisations, and 7502 providers). There was low-certainty evidence from a single study to suggest that public release of performance data may have differential effects on disadvantaged populations. There was no evidence about effects on healthcare utilisation decisions by purchasers, or adverse effects. AUTHORS' CONCLUSIONS: The existing evidence base is inadequate to directly inform policy and practice. Further studies should consider whether public release of performance data can improve patient outcomes, as well as healthcare processes.

The Need to Consider Longer-term Outcomes of Care: Racial/Ethnic Disparities Among Adult and Older Adult Emergency General Surgery Patients at 30, 90, and 180 Days.

OBJECTIVES: Following calls from the National Institutes of Health and American College of Surgeons for "urgently needed" research, the objectives of the present study were to (1) ascertain whether differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among adult (18-64 yr) and older adult (≥65 yr) emergency general surgery (EGS) patients; (2) vary by diagnostic category; and (3) are explained by variations in insurance, income, teaching status, hospital EGS volume, and a hospital's proportion of minority patients. BACKGROUND: Racial/ethnic disparities have been described in in-hospital and 30-day settings. How longer-term outcomes compare-a critical consideration for the lived experience of patients-has, however, only been limitedly considered. METHODS: Survival analysis of 2007 to 2011 California State Inpatient Database using Cox proportional hazards models. RESULTS: A total of 737,092 adults and 552,845 older adults were included. In both cohorts, significant differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions were found, pointing to persistently worse outcomes between non-Hispanic Black and White patients [180-d readmission hazard ratio (95% confidence interval):1.04 (1.03-1.06)] and paradoxically better outcomes among Hispanic adults [0.85 (0.84-0.86)] that were not encountered among Hispanic older adults [1.06 (1.04-1.07)]. Stratified results demonstrated robust morbidity and readmission trends between non-Hispanic Black and White patients for the majority of diagnostic categories, whereas variations in insurance/income/teaching status/EGS volume/proportion of minority patients all significantly altered the effect-combined accounting for up to 80% of risk-adjusted differences between racial/ethnic groups. CONCLUSIONS: Racial/ethnic disparities exist in longer-term outcomes of EGS patients and are, in part, determined by differences in factors associated with emergency care. Efforts such as these are needed to understand the interplay of influences-both in-hospital and during the equally critical, postacute phase-that underlie disparities' occurrence among surgical patients.

The Association Between Medicare Eligibility and Gains in Access to Rehabilitative Care: A National Regression Discontinuity Assessment of Patients Ages 64 Versus 65 Years.

OBJECTIVES: The aims of this study were to assess for changes in uninsured rates among trauma patients at age 64 versus 65 years and whether there are associated changes in post-discharge rehabilitation; determine whether changes are driven by rehabilitation provided at home, skilled nursing facilities (SNFs), or acute inpatient facilities; and determine whether changes vary among stratified subgroups of trauma-related "best-practice" factors. SUMMARY BACKGROUND DATA: Rehabilitation is an important component of high-quality trauma systems with access heavily influenced by insurance status. In the wake of policy changes affecting insurance coverage, it remains unknown the extent to which insurance changes associate with variations in rehabilitation access/use among otherwise similar patients. METHODS: Regression discontinuity models were used to assess for changes in insurance status and rehabilitation at age 64 versus 65 years among adults ages 54 to 75 years (±10 years age-related Medicare eligibility). Data were extracted from the 2007-2012 National Trauma Data Bank. RESULTS: A total of 305,198 patients were included; 40.1% were discharged to rehabilitation. Medicare eligibility was associated with an abrupt 6.4 (95% confidence interval: 5.8-7.0) percentage-point decline in uninsured and a 9.6 (95% confidence interval: 6.5-12.6) percentage-point increase in rehabilitation at age 64 versus 65 years, enabling an additional 1-in-10 patients to access rehabilitation. Differences were driven by SNF use and were greatest among patients with less-severe clinical presentations. Restriction based on Medicare-payment eligibility to patients with length of stay ≥3days (SNF requirement) and ≥1 "presumptive diagnosis codes" (inpatient facilities' 60% rule) demonstrated abrupt gains in both SNF and inpatient care. CONCLUSIONS: The results reveal the magnitude of changes in access to rehabilitation associated with changes in insurance coverage at age 65 years. Use of quasiexperimental models enabled meaningful consideration of health-policy change.

Are Older Adults With Hip Fractures Disadvantaged in Level 1 Trauma Centers?

BACKGROUND: Large regional hospitals achieve good outcomes for patients with complex conditions. However, recent studies have suggested that some patient groups might not benefit from treatment in higher-level trauma centers. OBJECTIVE: To test the hypothesis that older adults with isolated hip fractures experience delayed surgical treatment and worse clinical outcomes when treated in higher-level trauma centers. RESEARCH DESIGN: Retrospective cohort study using a statewide longitudinal database that captured 98% of inpatients within California (2007-2011). SUBJECTS: All older adults (aged 65 y and above) admitted with an isolated hip fracture who did not require interhospital transfer. MEASURES: Days to operation, length of stay, inhospital mortality, 30-day risk of unplanned readmission, 30-day venous thromboembolism, decubitus ulcers, and pneumonia. RESULTS: There were 91,401 patients, 6.1% of whom were treated in a level 1 trauma center (L1TC), 17.7% in a level 2 trauma center (L2TC), and 70.2% in a nontrauma center (NTC). Within multivariable logistic and generalized linear regression models, patients treated in L1TCs underwent surgery later (predicted mean difference: 0.30 d; 95% CI, 0.08-0.53), had prolonged inpatient stays (0.99 d, 0.40-1.59), and had higher odds of both 30-day readmission (aOR=1.62; 95% CI, 1.35-1.93) and venous thromboembolism (aOR=1.32, 1.01-1.74) relative to NTCs. There were no differences in mortality, decubitus ulcers, or pneumonias. L2TCs were not different from NTCs across any of the measured outcomes. CONCLUSIONS: Older adults with hip fractures may be disadvantaged in L1TCs. Further research should aim to develop our understanding of this disparity to ensure that all patient groups benefit from the resources and expertise available within these hospitals.

Access to post-discharge inpatient care after lower limb trauma.

BACKGROUND: Most hospitals in the United States are required to provide emergency care to all patients, regardless of insurance status. However, uninsured patients might be unable to access non-acute services, such as post-discharge inpatient care (PDIC). This could result in prolonged acute hospitalization. We tested the hypothesis that insurance status would be independently associated with both PDIC and length of stay (LOS). METHODS: An observational study was undertaken using the California State Inpatient Database (2007-2011), which captures 98% of patients admitted to hospital in California. All patients with a diagnosis of orthopedic lower limb trauma were identified using International Classification of Diseases, 9th Revision, Clinical Modification codes 820-828. Multivariable logistic and generalized linear regression models were used to adjust odds of PDIC and LOS for patient and hospital characteristics. RESULTS: There were 278,573 patients with orthopedic lower limb injuries, 160,828 (57.7%) of which received PDIC. Uninsured patients had lower odds of PDIC (adjusted odds ratio 0.20, 95% confidence interval 0.17-0.24) and significantly longer hospital LOS (predicted mean difference 1.06 [95% confidence interval 0.78-1.34] d) than those with private insurance. CONCLUSIONS: Lack of health insurance is associated with reduced access to PDIC and prolonged hospital LOS. This potential barrier to hospital discharge could reduce the number of trauma beds available for acutely injured patients.

Disfiguring Firearm Injuries in Children in the United States.

Firearms are a leading cause of injury and death among children in the United States. Most gun violence studies highlight mortality, but few have examined the morbidity in disfiguring injuries suffered by children. Using National Trauma Data Bank 2007-2015, children who suffered gunshot injuries and underwent procedures with lasting physical disfigurement formed the cohort of this study. We identified 28 593 children as victims of firearm injuries. Most were aged 13-18 (84%). There was a preponderance of male gender (86%) and black race/ethnicity (57%). Total mortality was 3774 (13%), and 1500 (5.4%) were identified with one or more disfigurements: 220 amputations, 191 craniectomy, 100 enucleation, 533 ileostomy/colostomy, and 557 tracheostomies. This report highlights the large toll firearm injuries take on American children, specifically in non-concealable disfigurements. These injuries are very impactful to their education and overall socialization and therefore must be a part of the discussion of gun violence in the United States.
